View larger. | NASA’s Cassini spacecraft captured this view of Saturn’s largest moon, Titan, with another moon of Saturn, Rhea, passing in front of it, on June 16, 2011. A new study shows that Titan’s atmosphere wobbles like a gyroscope. Why it does so, however, is still a mystery. Image via NASA/ JPL-Caltech/ Space Science Institute.
